To all wir/m, it may concern:

Beit known that we, Lnwis A. BROWN and ROBERT LANG, citizens of the United States, residing at St. Louis, Missouri, have invented a new and useful Brick-Machine, of which the following is a specification..

rThis invention relates to brick-machines;

and the object is to produce a machine consisting of a frame or support, compression devices .carried thereby and suitable adjustable formers or molds control] ed by the compression devices.

ln the drawings, wherein the preferred. form of the invention is illustrated, Figure 1 is a plan view of the machine. Fig. 2 is an end view. Fig. 3 is a cross-sectional view. Fig. 4 is a bottom view. Fig. 5 is a sectional view taken approximately on lthe line 5 5 of Fig. l. Fig. 6 is a perspective view of one of thel formers or molds. Fig. 7 is a perspective view of a brick or block formed in the machine.

Referring specifically to the various parts, 1 indicates a frame or support having a plurality of pairs of slots 2, the two slots comprising each pair being alined, as shown in igs. 1 and 4. Bearings 3 are provided on the under side of the frame or support 1, and shafts 4 are ournaled in said hearings. Right and left hand threads 5 are formed on said shafts. A bar 6 is provided across each series of the slots 2, said bars having threaded bearings 7, whereby they will be moved toward each other when the shafts 4 are turned, as hereinafter described. Profections 8, rigid with said bars 6, project t rough the slots 2, as shown in Fig. 5, and the projections on the different bars likewise move toward each other when the shafts 4 are turned. A pinion 9 is attached lto each shaft 4, and a gear 10, mounted upon a suitablysupported trunnion intermediate of said pinions, meshes with both of said pinions. A handle 11 affords means for turning said gear 10, and thereby the shafts 4.

For each machine there is provided a series of mold, or former supports 12, adapted to rest separately upon the frame or support 1, as shown. Said supports 12 are provided with slots which. when properly positioned register with the slots 2 and through which the projections 8 extend. Near one end of the support 1 is a rigid shoulder or brace 13,

which serves `as an .abutment for the .support 12 and similarly Aas a guide for the formers or molds. Near the opposite end yof the said support 1 is a bearing 14, which supports a screw-bolt 15,. Said screw-bolt is pivota-lly connected at its inner end to a compressionplate 16.

The molds .or formers are separate boxlike structures removably located upon the former-supports 12 when in use. For shaping small blocks or bricks one pair of the projections 8 for `each mold is sufficient; ybut whenlarge objects are to be shaped and a larger mold ris utilized `a greater number of the said proj ectionsare necessary properly to compress the mold and hold it in proper position. In all cases all the projections S on each bar 6 are held perfectly alined, so that absolute regularityas to size is assured. In the form shown there are several molds on the machine, and each mold consists .of two angular plates 17, arranged to form an opentop box, as clearly shown in Fig. 1, the side of each plate bearing against the end of the laterally-bent portion of its associate. These box-like molds are arranged between the member 13 and the compression-plate 16. By turning the screw-bolt Al5 the molds will be pressed closely together and so held.

In using the machine the shafts 4 are turned to move the projections 8 toward the outer extremities of the slots 2. Upon a previouslypositioned support 12 the molds are then adjusted between the two rows of projections 8. Within each mold a plate 18 is placed, said plates being of the same width as the molds and of uniform length. These plates prevent the plastic material that is poured into the molds from passing through the slots 2. After the plates 1S have been positioned the shafts 4 are turned to move the rows of projections 8 toward each other, and thereby move the mold members 17 until they are stopped by the plates 1S. Then the plastic material is poured into the molds, after which the mold-support 12 and the molds may be removed from the part 1 and another moldsupport and another set of molds may be placed thereon.

In some instances it may be desired to form blocks or bricks with an adhering plate. This form of block or brick is shown in Fig. 7, wherein the plate 19 adheres to the block 20,

ICO

said plate also being shown in empty mold in Figs. 3 and 5. The plates 19 in such instances are provided with angular edges 21, which project upward at about forty-five degrees when the plates are placed in the molds. Then when the plastic material is poured into the molds said edges 21. become embedded therein and rigidly adhere to the finished block or brick. The operation of the machine is the same in all instances.

By this machine blocks or bricks of various sizes may be made, though at each operation only one dimensionv can be molded. There may be variations within limits without departing from'the spirit and scope oi the invention, and we do not desire to restrict ourselves to inessential details; but

What we desire to secure by Letters Patent is l. A brick-machine comprising a series of molds, shafts` projections on the shafts, and means for rotating the shafts to move tne projections and parts ofthe molds and thereby diminish the size of the molds.

2. A brick-machine comprising a series of molds, a support therefor, projections adjacent to said molds, a handle, and mechanism controlled by the handle to move the projections and diminish the size of the molds.

3. .ln a brick-machine, a mold comprising two angular members forming an open-box structure, and manually-operable mechanism for moving both of said angular memposition in anv bers and thereby to diminish the dimensions ofthe mold.

4. ln a brick-machine, a support, a mold comprising two angular members, a plate removably positioned between said angular members, manually operable devices for compressing tne angular members together laterally, and manually-operable mechanism for movingI said angular members endwise.

5. In a brick-machine, a mold comprising two angular members, a plate removably positioned between said angular members, a

manually-operable device 'for moving said an# gular members laterally to compress them together, and manually-operable mechanism for moving said angular members endwise.

6. ln a brickanachine, a mold comprisin(T two angular members, 4a plate between sai angular members, a compression-plate at the side of one of said angular members., a manuallyeoperable device tor moving the compression-plate to bind the angular members together, and manually-operable mechanism for moving both of said angular members` endw ise, substantially as described.

ln testimony whereof we hereto affix our signatures in the presence of two Witnesses.
